Furthermore, changes in circumstances after the time of publication of the Information may impact on the accuracy of the information. The biologically effective dose and equivalent dose in 2Gy calculators are based on the Linear Quadratic Model. As with any model there are limitations including the lack of a time factor and its applicability for low doses per fraction (1.2Gy). The doses are calculated as a guideline to allow conversion and comparability of different fractionation schemes. Clinical decisions based on this are the responsibility of the radiation oncologist.
